That's exactly the combo I got-- SI-97 with the L1B 92mm Panaflo. Works great. I have it on a fan controller and run it at 7v when I'm not gaming or anything. Still keeps me at about 49c most of the time. When I game or do something that puts the cpu under load, I crank it up to full and temps drop to 45c under extended full load. This is all on my XM-M 2400+@3200 200X11. Even at full speed its very quiet.
I bought them both from Jab-tech, excellent experience dealing with them and great price on the si-97!
